Summary
DDOS attack on graphql endpoints
Details

An attacker could use a specially crafted graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. This mostly affects websites with publicly exposed and particularly large/complex graphql schemas.

If your Silverstripe CMS project does not expose a public facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this will likely further mitigate the risk.

Upgrade to silverstripe/graphql 4.2.3 or 4.1.2 or above to remedy the vulnerability.

Severity ?
7.5 (High)
